Invasive Species

What Are Invasive Species?

The State of Michigan has defined invasive species as non-native and whose introduction causes harm, or is likely to cause harm to Michigan’s economy, environment, or human health.

Many non-native species in Michigan, including fruits, vegetables, field crops, livestock and domestic animals, are important to our economy and lifestyle. Most non-native species are not harmful and may provide economic benefits. Invasive species cause harm when they out-compete native species by reproducing and spreading rapidly in areas where they have no natural controls or predators. Both the WLA and the WLTC take part in regional cooperative efforts that help us learn more and control the spread.
